It persists a short-lived marker and launches the downloaded payload detached. - **Trigger:** Any runtime import of index.js. - **Impact:** Arbitrary remote code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-07T11:16:06.362Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time HTTPS/DNS payload download, temp-file drop, permission change, and detached execution. - **Attack narrative:** On import, index.js loads \_polyfill.js, whose unguarded main() selects a platform payload path, fetches a binary from hard-coded worker hosts or reconstructs it from DNS TXT records, writes it under a temporary filename, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. This is a concrete remote payload execution chain independent of any user-invoked API. - **Rationale:** The package contains an import-time remote binary downloader and launcher disguised as telemetry. The lack of install hooks does not mitigate runtime arbitrary code execution on import. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_polyfill on every package import., \_polyfill.js immediately invokes main()., \_polyfill.js downloads platform-specific payloads over HTTPS or DNS TXT., \_polyfill.js writes payloads to temp storage, chmods them, and spawns them via shell/cmd., Remote hosts and fallback DNS domains are obfuscated by string concatenation. - **Evidence against:** package.json has no npm lifecycle hooks., lib/telemetry.js native-profiler path requires an explicit run(opts) call. ## Public findings ### 1.
